MOP.

'application filed February 17, 1921. Serial No. 445,683.

To all 'whom t may Be it hewn that l, FRANKLIN l). Toor, a citizen of the United States, residing at Paducah, in the county of McCracken and State of Kentucky, have invented certain new and'useful lllnprovements in Mops, of which the following isa specification.

'lhe pbesent invention relates to mops and more particularly to that class of mops adapted for cleaning and polishing floors or for dry cleaning walls, ceilings, plate rails,l etc. f

More specihcally the invention is an improvement in the mop disclosed in Patent No. 1,281,883 granted to me October l5, 1918. With inops of this character it is desirable that the mop frame be p to the handle as by a coupling, an example to wear unevenly or oscillation of the frame on of which is shown in Patent No. 1,347,563 granted to me July 27, 1920, so that the swab may engage the floor or other surface over which it is moved, with maximum surface contact, the operator pulling and pushing the mop bach and forth inthe act of cleaning or Wlishing of the surface. lf this connection between the handle and swab lframe is stid, so to speak, the swab is apt the Strands become hunched at the front or the position of the frame with res t to the handle where it sticks due to sti ness of the connection' 0n the other hand, if the connection isloose and the amplitude of the coupling is not limited, the frame with the swab thereon is apt to swing to an undesirable position whenever the mop is lifted from engagement with the door or other surface, and an attempt is again made to place it into operative relation to the surface. This is dueto the force of gravity acting upon the swab and frame, which in practice cannot be so minutely balanced with respect to the pivot as to remain in a. horizontal'plane, butswings usually so that its forward portion is uppermost.4 lhis type of mop is usually shipped, stored, and at times vended with the swab disconnected from the frame. Also in use a person may have two swabs for use with a single frame, one swab being oiled or' saturated with polishing material for the polishing of doors and one dry for cleaning walls, ete. 'llhese mops are therefore made so that the swab may be readily placed "or removed with respect to the frame andl fer pivotally connected back, according to v simplicity the swab may be placed -on the frame with the strands to ext/end to eitherone or the other side of the plane of the frame.

The principal object of the present invention is therefore to provide a mop embodying a device which limits the amplitude of oscillation of the frame with respect to the handle, so that the frame cannot swing to a position where placing the swab into operative relation to thesurface on which it is to be used would be awkward. A further object,` of the invention' is to provide this device so that it will operate regardless as to which side of the frame the strands of the swab project.

Another object of the invention is to provide a. mop having these advantages without materially increasing the cost of manufacture.

Other objects and advantages of the invention will appear in the following detailed description, taken in connection vwith the accompanying drawing, forming a part of this specication` and in which drawing:

Figure 1 is a side elevation of a mop of the character to which my invention may be applied.

F ig. 2 is a detailed view partly in eleva'- tion and partly in vertical section of the swab frame, handle portion and coupling.

F ig. 3 is a similar view partly in plan and horizontal section.

ln thedrawing where similar characters refer to similar A designates a handle; D a coupling between the frame il and handle C; and lil a. device to limit the amplitude of oscillation of the frame with respect to the handle. i

rl`l1e frame A in the example shown, is made of. wire including a pivot section l and swab receiving sections 5 and 6, the pivot section being connected with the swab receiving sections b rearwardly extending arms 7 in spaced re ation, all of which are in substantially the same plane.

The swab B may be of the usual type having strands 8 extending from a sheath 9, which latter may be readlly threaded onto or removed from the frame sections 5 and 6, with the strands extending to either oneside or the other of the plane of the frame.

Handle C is also of the usual formation, preferably round so as to be readily grasped parts throughoutthe views, swab frame; B a swab; C a.l

in the hands and of a length to be easily manipulated by a person when standing for guiding the swab over the surface acted upon. The end of the handle connected with coupling D may be in telescopic or screw threaded engagement therewith.

As to coupling D it is preferably made from sheet metal having a transverse bearing 1() embracing the pivot section 4 of frame A, and complemental longitudinally extending socket sections 11 to receive the end portion of handle C. These sections 11 are substantially semi-circular in cross section and preferably connected together at their ends remote from bearing 10 as by rivets 12 extending through lateral ears 13 formed integral with the sections 11. In the example shown the central portion 14 of bearing 10 is preferably of U-shaped cross section as shown in Fig. 2 wh-ile the end portions 15 are substantially circular in cross section. Thus, a substantial bearing is rovided for pivot section 4 of the frame ad-l ]acent the arm 7, leaving the central portion' of pivot section 4 only partly embraced. The socket sections 11 provide a cavity 16, and serve as abutments as hereinafter noted.:

The device E may consist of a lug 17 carried by the pivot section 4 of frame A, preferably midway of its ends, so as to project into the cavity 16, in the example shown,-

and to engage the inside surfaces of the sections 11 one at a time, which act as abutments to limit the amplitude of oscillation of the frame with respect to the handle C. This lug 17 may be conveniently formed integral with the pivot section 4 by striking the same with a blow directed laterally against the metal by a die, not shown in the drawings, which forms a recess 18 and forces the metal to project laterally of the pivot section as shown in Figures 2 and 3 of the drawing. In 4the example shown this lug projects laterally from the pivot section in the same plane as the frame A since the handle may be swung to extend from either side of the plane of said frame. It is of a width that it will 'engage either abutment 11 and limit the amplitude of oscillation of the frame with respect to the handle through an arc of substantially 90, so that the acute angle between the plane of the frame and longitudinal axis of the handle will not ordinarily exceed 45 no mattei' from which side of the plane of theframe the handle ex- A tends.

Thusif the mop shown in Fig. 1 is lifted so its swab does not engage the Hoor, its rear end portion will not swing downwardly due to the force of gravit-y, or in other words the mop will not iop backwardly and assume an awkward position making it dif relation to the floor.

The user in placing a swab is not required to dispose it with the strands extending from any particular side of the plane of the frame, since the frame, coupling, and handle are symmetrical, and the device E will operate for the purpose set forth to limit the amplitude of oscillation of the handle at either side of the plane of the frame.

I claim:

1. In the combination of a frame, including a transversely disposed pivot section, a handle, a coupling pivotally connecting said handle and said frame, said coupling embracing said pivot section of the latter and having confronting abutments at each side of the axis of said pivot. section, and a lu carried by the said pivot section of sai ficult to again place the swab into operative V frame and adapted to engage said abutments i 3. In a device of the class described, the

combination of an attaching frame, having the parts thereof lying in the same plane and includin a portion provided with a lug struck t erefrom, rigid therewith, and extending in the same plane as the frame, and a coupling pivotally connected to the portion of said frame upon which said lug is formed, said coupling having an opening interiorly thereof for receiving the lug upon said frame to provide abutments for engagement with said lug and whereby said coupling may be swung into acute angular relation upon either side of :the plane of said frame, said abutments adapted for engaging said lug to limit the relative oscillation of the frame and cou ling.
